This gallium evaporation material has a melting point of 30°C, requiring storage below this temperature to prevent premature melting. Deposition requires compatibility with Mo/W/Ta boat or graphite/alumina crucible sources, with thermal/resistive evaporation as the preferred method.
- Melting Point Constraint: Store below 30°C to maintain solid piece form and avoid premature melting during storage and handling.
- Source Compatibility Constraint: Use only with Mo/W/Ta boat or graphite/alumina crucible evaporation sources to prevent contamination or equipment damage.
- Evaporation Method Constraint: Thermal/resistive evaporation is the preferred method; low-power e-beam is an optional alternative.
What are the implications of gallium's low melting point (30°C) for thermal evaporation deposition compared to higher-melting-point metals?
Gallium's melting point of 30°C causes it to liquefy well below typical evaporation temperatures, which can lead to premature melting and potential source wetting if not controlled. The product is specified for thermal/resistive evaporation using Mo/W/Ta boats or graphite/alumina crucibles, and the low melting point enables low-power operation but requires careful temperature management to avoid excessive liquid flow.
Can gallium evaporation material be used in e-beam evaporation systems, and what crucible materials are compatible?
Yes, low-power e-beam evaporation is listed as an optional method, though thermal/resistive evaporation is preferred. Compatible crucible materials include Mo, W, or Ta boats as well as graphite or alumina crucibles, and the pieces 1–5 mm form factor is designed to load easily into these sources.
What are the storage and handling requirements for gallium evaporation material given its low melting point and 99.99% purity?
Because gallium melts at 30°C, storage below this temperature in a dry, sealed container is recommended to maintain the solid pieces form and prevent contamination of the 99.99% purity material. Users should consult the safety data sheet for specific shipment conditions and handling precautions, and the product should be kept in its original packaging until use.
This research-grade gallium evaporation material offers 99.99% purity in pieces 1-5 mm, suitable for thermal or low-power e-beam deposition. Its low melting point of 30°C simplifies thermal evaporation but demands controlled storage and careful handling to prevent premature melting.
Positive
- High-purity 99.99% gallium: Defined 99.99% purity and material identity enable reliable deposition process matching and consistent film quality.
- Versatile evaporation method compatibility: Thermal/resistive evaporation preferred, with low-power e-beam optional using Mo/W/Ta boats or graphite/alumina crucibles.
Trade-offs
- Low melting point requires controlled storage: With a melting point of 30°C, gallium can liquefy at ambient temperatures, necessitating cool storage and careful handling to avoid phase change.
- Requires source hardware and process matching: Evaporation source geometry and process route must be carefully matched to gallium's low melting point and film requirements to achieve optimal deposition.
